I got the axle out and proceeded to ankle grind what looked just like the part in my bearing kit. But it was a single piece attached to what I can only assume is a speed sender(like a cog) that gives the speed sensor something to count. now I'm going to have to replace that part but I want to know how the hell I am supposed to have got it off in the first place. There is absolutely no informstion on the internet about what this part is. all the forums on the net and all the service manuals I have downloaded are just like "take of the axle take gring of the bearing put the new bearing on" What gives??? please help with info.
